Specification of LOSQEVQ.

To all whom it may concern:

. Be it known that l, Mourns Karina citizen of the United States, and resident of Passaic, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Soldering-Mation.

The object of my invention is to provide simple and efiicient means for expeditiously soldering different parts together, and is particularly adapted for soldering screw caps on sides of tubes or spouts.

Tubes or spouts for certain kinds oi cans are frequently provided with screw caps soldered to the sides of the former, so that such caps may act as closures for cans or containers, and when unscrewed from the can or container the threaded cap at one end of the tube or spout may be screwed upon the can for attaching the former thereto. Such caps have frequently been soldered to the sides of spouts by hand operation which by means of my invention such soldering of the parts together may be carried out accu is not limited to soldering such described parts together.

My invention comprises novel details of improvement and combinations of parts that will be more fully hereinafterset forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings rorming part hereof. wherein,

Figure 1 is a partly sectional. side elevation of a soldering machine embodying my invention; Fig. E2 is an enlarged side view of a portion ot the machine, partly in section on the plane of the line 2, 2, in Fig. 3; Fig. 3 is an edge view, partly in section substantially on the line 3, 3, in Fig. 2; Fig. 4 is a detail fr nt view looking from the left in Fig. 2;. Fig. 5 is a detail section of modified means for spraying water upon. the soldered parts.

Similar numerals of reference indicatecorresponding parts in the several views.

The numeral 1 indicates a suitable frame tit standard, which may be supported upon atable or the like 2, said frame being pro 3, which maybe raised and lowered. by a lever d movably connected with said plunger at 5 and piyotally supported at 6 upon Letters Patent. I

'frame 1. Lever imay be operated by a treadle 7 connected by rod 8 with said lever.

9 indicates a counterweight on lever 4. Plunger 3 is provided with a soldering iron or the like 3 shown having a recess 3* at its lower end adapted to receive the article to be soldered such as a tube or spout 10. Soldering iron 3 is shown secured to plunger 3 by screw 16. Beneath soldering iron 3* is a rest 1l,-shown provided with a recess 11 to receive the part. such as a cap 12, to be soldered to the side oftube, spout or nozzle 10. Spout 10 is shown provided with an ordinary screw cap 105 at/bne nd. Suitable means are provided fie r heating soldering iron 3 For this purpose I have shown a burner 13, in the nature of a Bunsen burner, shown connected with gas supply pipe 14. Burner, 13 is shown located in such position (Fig. 1) that when soldering iron 3 is raised the flame from the burner will be projected against the soldering iron.

At 15 is a shield opposed to the flame and carried by plunger 3 in any suitable manner. The solder 17, shown in the form of solderwire, may be guided through a tube or other suitable means 18, shown carried. by frame 1, so as to be projected over tube or spout l0 between the latter and soldering iron 3*. Means are provided for feeding solder wire step by step over the articles to be soldered, and the lower edge 3 of the soldering iron is adapted to cut or melt oil the end of the solder extending from guide 18 as the soldering iron descends. The means shown for feeding the solder wire forwardly. step by step, comprise opposed wheels receiving the solder wire between them. I have shown a toothed wheel 20 and an opposed grooved wheel 21 mounted respectively to rotate upon studs 22, 23, carried by frame 1,'be tween which wheels the solder wire 17 is passed.

At 24. is a ratchet wheel connected with wheel 20 and operated. by a spring pressed pawl 25, shown carried by one arm of a bell crank lever 26 journaled upon or secured to stud E22, and connected at its other arm by a rod 27 and spring 27 with treadle 7, whereby when said treadle is depressed the solder wire 17 will be projected forwardly the required distance. Solder wire 17 may pass to guide 18 from a reel 28 and be guided over apulley 29 upon table 2. To permit further depression of treadle 7, after the solder wire has been fed, a spring 27 is provided. I have shown spring 27 inclosed in a tube or casing 27 within which headed rod 27 slides, spring 27" being interposed between the bottom of tube 27 and the head of rod 27, the latter being pivotally connected with treadle 7. Nut may engage the stop or plate 2 when the treadle is depressed to limit the rotation of ratchet wheel 24 and thereby to regulate the amount offeed'of the solder wire, for which purpose said nut may be adjusted along rod 23. I have also provided means for cooling the soldered parts after the solder has been applied thereto. This may be accomplished by blowing air or spraying water against the soldered parts, such as against the soldered tube or spout 10 and its cap 12. For this purpose 1 preferably provide a delivery nozzle 30, shown connected with a supply pipe 31,and having an air controlling valve 32 whose stem 32* is connected by an arm 33 with rod 34, said rod being connected with treadle 7.

Air under pressure may be supplied to pipe 31 and when the treadle is depressed andthe valve closed the air flowing from nozzle is cut oil, and when the 'treadle is released .br raised the air flows directly from nozzle 30 upon the soldered parts. i

In Fig. 5 I have shown means for cooling the soldered parts by aspirated water. For this purpose a jet or nozzle 31 communicating with a water supply is locatedwithin the piping 31, and thus as air is blown through pipe 31 it will draw water from nozzle 31 and cause cooling spray to he directed upon the soldered parts.

In the operation of my machine the parts to be soldered are placed together upon the seat or rest 11, as for instance, cap 12 is placed upon seat or rest 11 and the spout ornozzle 10 is placed over the cap (Fig. 4) and then treadle 7 is depressed. The flow of air or aspirated water to nozzle 30 is then cut ofi, the solder wire projected over the articles to be soldered, and the nut 25 meeting the stop 2 limits the feeding ofthe solder while treadle 7 may continue to be depressed by reason of the compression ofspring 27, and lever 4 is rocked to depress plunger 3 and the heated soldering iron 3. The soldering iron cuts or melts oil the portion of the solder 17 projecting from-guide 18 and forces it down upon the articles, and the parts are held in such position until the heated soldering iron properly melts the solder to secure the parts together. The treadle is then released, the soldering iron is raised, pawl 25 moves back and valve 32 opens, thereupon air or aspirated water is blown or ejected from nozzle 30 against the soldered parts to cool the same. Such parts are then removed, and the operations may be repeated as desired.

By means of my invention it will be ap parent that the operation of soldering the parts together, such as spouts to the caps, can be accomplished with expedition and accuracy, without wasting solder, and substantially the proper amount of solder may be applied at each operation.

While I have shown a ratchet and pawl for feeding the soldered wire, it will be understood that the feeding wheels may operate by frictional contact against the solder wire or that the solder wire may be fed in any well knownmanner, and that any desired parts may be soldered together by suitably arraying the mechanism described toreceive and act upon such parts.
